LAND LEVELR.

Appn'cation filed August 1, 1922.y serieu No. 573,945.

To (zZZ Iifi/10m it may concern.: i Beit known that I, WILLIAM H; Monson, a citizen of the United States of America, residing at Sandose, in the county of Santa Clara and State of California', have invented certain new and useful Improvements in Land Iievelers,.ot` which .the *followingis a specification, i v f l The present invention relates rto an im` proved land leveler or drag for use in culti-A rating the soil, grading, and smoothing the land surface. The primaryy object ofthe .invention is the provision of a strong and well braced implement of this character,

" which is durable, comparatively simple in construction and operation, of i suillcient weight for dragging over the ground surface with a. leveling action and scraping of the surface andwhich is capable of adjustment for adapting the scrapers to various kinds oit soi. and diii'erent conditions to be overcomeA in leveling operations.

The invention in its physical embodiment found to be comparatively inexpensive in cost of material and manufacture and has been for some time in actual and successful operation. kCertain novel combinations and arrangements of parts constitute the invention-and theywill be pointed out in the appended claims.

In the accompanying" drawings I have illustrated one complete example oit the physical embodyingmy invention, the several scrap'- wherein the vparts arecombined and arrangedl according to the best mode lha-vey thus far devised for the successful reduction to practice of the invention, but it will be understood that changes and alterations are contemplated and. may loe-made in the `illustrated form oi' the inventionwithout departing trom they spirit ofmyl invention.

Figure 1 is a plan view'ot the implement embodiment of my invention,`

in horizontal po-` tional viewthrough the implement showing the scraper ybars injadjusted tilted position;

Figure 5 .is an enlarged detail sectional lview;transversely of one ofthe scraper bars and showing; also the bolt-holes yin 'the angle bracketskv I The implement now' in; actualV use approrimates the structure shown'i'n Lthe draw-l ings, and in 'carrying out my'invention and constructing the VLleveler I employ a series of transversely arranged scrapers indicated bythe numerals :1, 2, `3, 4. A larger number -or'a smallernumber of thes'escrapers may be used if desired, and while 'I have shown i the Scrapers as channel beams with dependA ing flanges 5, it will be understood that kother shapes,` such as Tbeams or angle beams may be used. The depending flanges are'designed andlocated in proper posi-y tion to travel over the surface of the ground or soil as scrapers vor drags for grading,

smoothing, and leveling the surtace` and the weightfofthese transverse beams is sut icient tb hold the implement to theground,

to cut to the required depth.

f These transversescrapers are arrangedin parallelism and properly spaced apart,'and on their upper plates are attached angle brackets all df which are similarin size and shape and comprising horizontal vflanges 6 and vertical flanges' 7 n' Ther angle brackets, as shown yin Figure lare attached near each end, and one at the middle of each of the Scrapers, and arrangedlin three rows on the upper suriace ofthe implement, with their vertical flanges or webs 7 in ,'alinement.` And by meansv of these brackets the Scrapers are connected with a pair of lateral bars 8 and '9,and yan intermediate bar 10. `'Ihese three bars are fashioned of flat metal :plates oi the required dimensions, which extend longitudinallf,7 of the implemenuand each bracket is connected with'each longitudinal bar by means oi a pairof bolts 11 and 12. The bolts :are passed through boltholes 8' ar-, ranged in pairsl inthe vthree longitudinal bars, and the Iianges 7 of the angle brackets "lll are providedwith complementary bolt holes 13, 14 15, 16, for thefbolts. The 'bolts 11 in eachk caseare adapted to act as pivot bolts and the boltsy 12 vare adapted to act f as clamp bolts-forl the pivot boltsin adjusting or tilting the Scrapers from their horizontal positions. Thus in Figure 4L 1t will be seen that the Scrapers are each capable of independent adjustment by removing the bolts i2 and loosening the nuts 17 of the bolts il, then swinging the scraper bar and its brackets to desired position, after which adjustment, the nuts l? may be applied to the bolts ll and l2 and tightened to hold the brackets in rigid relation to the several bars S, 9, l0. l have found that this means oit adjusting the implement .is simple and expeditious, but it Will be kunderstood that other adjusting means, as for instance levers and connecting links may be used rin connection with the scrapers to simultaneously more them to adjusted position. In such l event the arcuate series ot bolt holes lll, l5,

lt), in the brackets, will be dispensed with and each tlange 7 of the brackets will be Vfashioned with an arcuate slot in place .of the series oi holes.

The angle brackets are rigidly and securely attached to the upper plates of the channel beams or scrapers yby means ot rivets i8, applied in suitable number and joining together the top plates et the several scrapers .iith the horizontal llanges ot the brackets. dit the rear oitthe implement means are provided for cutting into the surface of the soil or ground, and tor this purpose the rear flange Voit the rear scraper 4c isprovided with a series of spaced openings 19 extending throughout the length oi" the llange, the desired distance apart.. These openings are designed to receive the threaded bolt heads 2O of the teeth Q1 ot case hardened steel, which project horizontally and rearwardlyol the scraper i With their tlatfaces in vertical planes and their cutting edges adapted to enter the soil below the surface lwhen the scraper 4 is tilted to adjusted position, as in Figure 4.

'he threaded shanks or bolts Q0 of the teeth are passed through the holes .i9 and clamped therein by means ot the clamping bolts 22 and 23 bearing against the inner and outer `laces of the depending flange of the scraper, Which thus .hold th\ teeth in igid and lixed relationship to the scraper.

The two side bars 8 and 9, as seen in Figure l are utilized as draft bars, and at their front perforated ends 2e, 2a, `are bent inwardly' and joined by the draft chain to whichsuitable power, as mechanical or horse power may be applied for dragging the implement.

At l0 the rear end of the `center bar l0 is kextended and perforated to form means for attachment oa second implement it' desired to lbe .used as an additional section ory unit ot this implement.

To protect ktrees of an orchard when the implement is used thereimand for other protective purposes, l utilize apair ot lateral shields or side guard-bars 26 and 27 which project beyond the extremities ofV the Scrapers to prevent contact ot these extremities with objects. The guard bars extend longitudinally ot the implement and are fixed, as by rivets to the main bars 8 and 9, at their respective outer faces. At the front of the implement these guard bars are bent inwardly as at 28 to form obliquely disposed guards to turn dovvn Weeds and push the Weeds or other growth to the respective sides of the implement to prevent catching on the implement.

From the above description taken in connection with my drawings it Will be evident that the implement as il ustrated and new used is capable. of tullilling` the requirements o' a most ,elilcient device, and that it is coraparatively simple in construction, may be manufactured at a minimum of cost, and may with facility be adjusted and adapted for various uses on the farm and under other .conditions required of such an imnlement.

Having thus Jfully described my invention, what l claim as nenT and desire to secure by Letters Patent is l. r)The combination with a series ct transversely arranged channel-beam Scrapers haring' a plurality ot angle brackets attached thereto and arranged lin rovvs, said angle brackets each having a single bolt hole and a spaced series of bolt holes arrangedr in the arc of a circle with the single bolt hole as a center, of longitudinally disposed draft bars disposed above said Scrapers, bolt connect ing each bracket with a. bar and adapted to :term a pivot, and a Vsecond ,bolt tor each bracket passed through a selected hole ot a series and adapted to form a clamp bolt.

2. The combination With a serie-s ot transversely arranged channel-beam scrapers including a scraper having rearwardly eX- tending teeth, of a plurality of brackets on each scraper arranged in rows,.longitudi nally disposed draft bars and an intcrme` diate bar above said scrapers, a bolt connccting each bracket with a bar and adapted to form a pivot and a second bolt 'for each bracket adapted to form a` clamp bolt.

3. The combination in an implement as described rvith a series of transversely arranged channel beam scrapers ,including a scraper having rearwardly extending teeth, of a plurality of angle brackets attached to j said Scrapers and arranged in roivs, the vertical tlange ort cach bracket having a bolt hole and a spaced arcuate series oi bolt holes, an intermediate bar and lateral draft bars longitudinally disposed above the scrapers, laterally projecting guard bars attached to said draft bars, and a pair of bolts connecting each vertical liange with its respective longitudinal bar.

in testimony whereof l have atliied my signature. i l l/VILLIAM H. ll/.lOr-TROE.
